Description

Track walking tea picking machine

technical field

The utility model relates to a track walking type tea picking machine.

Background technique

Tea garden picking is a tea garden management operation with a long history. my country is the birthplace of tea and the country that produces the most tea. Tea gardens in my country are widely planted in the soil and other environments of low mountains and hills. First, efficient tea picking is an important step to increase tea production. There are two main types of tea picking machines: single backpack type and double type. The track-travel type tea picking machine is a kind of tea picking machine with reliable power, convenient operation and suitable for large-scale tea gardens. Due to the factors of terrain and geological conditions, the tire-type tea picking machine is restricted from entering the tea garden. The use of rails can overcome the problem of complex road conditions. . At present, track walking is widely used in complex road conditions such as mountains and hills. The single-person knapsack and double-lift tea picking machines are only suitable for small-scale tea gardens with relatively flat terrain. Due to factors such as small operation width, large vibration, and high labor intensity, the amount of tea plucked is far less than the demand for tea. The double lift tea picking machine is more complicated and consists of five parts: gasoline engine, air duct, deceleration mechanism, and cutter frame. Although the cutting width can meet the operation requirements, in actual operation, two people are needed on the left and right sides of the tea picking machine. Lifting, it also requires people to hang the leaf bag behind the tea picking machine to facilitate the collection of the picked tea leaves, and the labor cost is too high. Therefore, it is not suitable for tea picking in modern tea gardens. With the development of economy and technology and the development of agricultural modernization, on the one hand, people's demand for tea is increasing, and on the other hand, the scale of tea gardens is getting larger and larger, and large-scale tea production needs to be backed by tea mechanization. Today's tea picking machines that can be used for large-scale tea picking are larger and have limited flexibility, and are not suitable for mountains and hills, and the height of the tea picking machine cannot be freely adjusted for plants with different growth vigor. The single-person knapsack and double-lift tea picking machines suitable for mountains and hills are also faced with the problems of labor shortage in rural areas and low picking efficiency. It can save manpower and improve work efficiency.

The track-type walking tea picking machine usually needs to lay two tracks and install the traveling mechanism. The structure of the traveling mechanism is generally a sheave. Compared with the general tea picking machine, the track-travel tea picking machine has the advantages of high tea picking efficiency, good operation flexibility, strong ability to adapt to the working environment, and can realize the picking of hilly and lowland tea gardens. Since the above two kinds of tea picking machines are mostly used as the main tea picking tools in the tea picking work, combined with the previous tea picking effects, it can basically meet the needs of tea picking, but in today's increasingly fierce competition in the tea market, The traditional tea picking machinery has a lot of room for improvement in the minds of the majority of tea farmers. It has good economic value and social significance to develop a set of track-traveled tea picking machines that can adjust their structure according to the size of the tea garden and plant growth and adapt to lowlands and hills.
